PERMANENT WAY FOR RAiLROADS.

SPECIFICATION forming part of Letters Patent No. 372,703, dated November 8, 1887.

(No model.)

To all whom it may concern.-

Be it known that I, Isaac A. PERRY, a citizen of the United States and a resident of Vi/ilinington, Delaware, have invented certain Improvements in the Permanent \Vays of Railroads,of which the following is a specification.

One object of my invention is to provide a strong and secure foundation for the rails of the track, a further object being to utilize old rails in the formation of a cross tie or sill, and a still further object being to provide for the secure clamping of the track-rails without the use of the usual spikes and bolts and without the necessity of boring or punching the rails for the reception of securing-bolts.

In the accompanying drawings, Figure 1 is a perspective view of a railroad-sill and railchairs constructed in accordance with my invention; Fig. 2, a transverse section through the end of one of the sills, showing, partly in longitudinal section and partly in elevation, one of the improved rail-supporting chairs; Fig. 3, a transverse section of said rail-supporting chair; Fig. 4, a sectional plan on the line 1 2, Fig. 3; Fig. 5, a View similar to Fig. 2, but showing some of the parts in different position; Fig. 6, a plan view, partly in section, of the base-block of the rail-chair without the clamps and illustrating some of the minor features of my invention; and Fig. 7, a transverse section of the rail-support shown in Fig. 6, with clamps constructed for use with a pair of guard-rails.

The cross tie or sill shown in Figs. 1 to 5 consists of two beams or girders, A A, each of which consists, preferably, of asection, of proper length, of an old or worn-out railroadrail. In carrying out my invention, however, but one girder may be used, or there may be more than two, if desired.

Each of the opposite railsupportiug chairs consists of abase-block, B, in which are longitudinal openings for the reception of the heads and upper portion of the webs of the girders A A. In the top of this base-block is formed a recess for the reception of the base-plate E of one of the clamps D of the rail-chair, one end of this recess being beveled for the reception of the beveled end of a tongue, at, on said base-plate, as shown in Fig. 8, a tongue, I), projecting downward from the opposite end one side of the base-block B.

In the clamp D is formed a beveled recess for the reception of the opposite clamp, D, which is beveled for adaptation to said recess, as shown in Fig. 4, so that on driving said clamp D longitudinally into the recess it is caused to bind laterally upon the flange and web of the rail, which is thus securely confined, the withdrawal of the clamp D after it has been driven into place being prevented by the engagement therewith of the upturned end (1 of the lockingbolt F, as shown in Fig. 2. By slightly loosening the nut f, however, the bolt F maybe moved longitudinally to such an extent that its upturned end will be free from the clamp D, and this end can then be turned down, as shown in Fig. 5, so as not to interfere with the longitudinal withdrawal of said clamp D, and the rail can be readily removed without disturbing the fixed clamp D or the base-block B. The whole supporting -chair and its base-block can, however, be readily removed from the girder forming the crosstie on first withdrawing the bolt F.

In order to prevent undue lateral strain on the bolt F, which might occur if said bolt was the only means of retaining the railchair laterally on the girders A, I notch said girders, preferably in their inner flanges, for the reception of keys m, Fig. 6, which are driven through openings in the base-block B of the chair, the clamp D bearing upon these keys, as shown in Fig. 5, so as to prevent them from becoming loose. This construction is of special advantage when the girders A are short, as in Fig. 6that is to say, when said girders do not extend across the track, but simply form a foundation for the chair. In such case I connect the opposite chairs by means of a tie-bar, M, which is preferably provided at each end with a dovetailed tongue, or, adapted to a dovetailed recess in the base-block of the chair, as shown in Fig. 6, and retained therein by the base-plate E of the rail-clamp. (See Fig. 7

In adapting my improved rail-chair to the support of guard-rails, a filling-block, D, is employed, as shown in Fig. 7, the fixed clamp D being constructed to bear against the outer face of one of the rails, and'the adjustable clamp D bearing against the outerface of the opposite rail, as shown in said figure, the construction of the chair in other respects, however, being the same as when a single rail is supported thereby.

Iclaim as my invention 7 l. The combination of one or more transverse girders, the base-block adapted thereto, the bolt passing through the base-block and girders, the keys adapted to seats in the baseblock and girders, and track-rail clamps secured to the baseblock, all substantially as specified.

2. The combination of one or more transverse girders, the base-block, the confiningbolt passing through the base-block and gird-- ers, keys adapted to seats in the base-block and girders, and track-rail clamps secured to the baseblock and confining the keys in place therein, all substantially as specified.

3. The combination of the opposite rails, a supporting structure for each rail, consisting of one or more transverse girders and a baseblock secured thereto, a connecting-bar having tongues adapted to recesses in said baseblocks, and rail-clamps which overlap and secure said tongues, all substantially as speci- 4. The combination of one or more girders forming the cross-tie or foundation structure, the base-block adapted thereto, the fixed railclamp havinga tongue projecting through said baseblock, and the transverse boltserving both to secure the base-block to the cross-tie or foundation structure and to confine the railend for retaining said movable rail-clamp, all

substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
